WARREN MeAn'rHUn, JR., or PHOENIX, ARIZONA.

RADIATOR-CAP.

` Application filed May 2,

To all whom it may concern.'

Be it known that I, WARREN MQARTHUR, Jr., a citizen of the United States, residing in Phoenix, in the county of Maricopa and State of Arizona, have invented a new and useful Improvement in Radiator-Caps, of

Whichthe following is a specification.

My invention relates toI caps lo r closuresv for automobile radiators and the like, in-

cluding such tanks and receptacles as it is adapted for, and has for its principal objects to provide as an article of manufacture a tank-closing device which may be readily applied to the necks of various standard forms 'of radiators, either when the parts are originally assembled inmanufacture or to replace an originally provided cap which has been lost or removed; also to thereby improve the artistic appearance of the radiator and Aautomobile and make much more convenient the opening and closing of the neck through which accessis had to the interior of the receptacle, for filling and other purposes. j

Vith such objects in view, as well as other advantages which may be incident to the use of the improvements, the invention consists in the parts and combinations thereof hereinafter set forth and claimed, with the' understanding that 4the several necessary elements constituting the same may .be varied in proportions and arrangement with out departing from the nature and scope of the invention. l

In order to l make the invention more clearly understood there are shownin the accompanying drawings means for carrying the same -into practical effect, without limiting the improvements, in their ,useful ap# plications, to the particular constructions which, for the purpose of explanation, have been made the subject of illustratidn. In the said drawings: 'j

Figurel is a vertical sectio'nalview of a portion of a radiator and casing of a standard or conventional form, having applied thereto a cap embodying my invention.

Fig. 2 is an elevation of the cap,

Fig. 3 is a vertical sectional view of the sleeve. T

Fig. 4 is a cross section on line IV-IV of Fig. 3.

Fig. 5 is a verticalfsection of a radiator neck and of the sleeve and its securing Specification of Letters Patent.

means, the securing ring or flange being in this `instance screwed within the sleeve.

- `F 1g. Gris a similar view, in which the ring 1s screwed within the sleeve and bears on the top of the sleeve, the sleeve being sccured to the neck by set screws.

Fig'. 7 is a similar view, the ring being screwed Within the sleeve and to the exterior of the neck.

Fig. Sis a similar View, partly in elevation, the sleeve being screwed directly to an exteriorly screw threaded neck.

Referring to the drawings, l is the radiator body, 2 the neck thereof and 3 the radiator casing, these parts being such as are in common use or of any improved and suitable construction. l is the sleeve of my cap or closure mad open at the top and bottom and 4adapted to be applied to the neck 2 so as to inclose the same, and preferably to bear on the casing 8 and clamp the saine at points around the base of the neck.

4shape and providing its lower edge with an v out-turned flange 5; but the sleeve maybe' of cast, metal, and may bear directly on the radiator body or tank. 6 is a iiange or ring formed with or suitably crimped to or screwed without or within the upper part' of the sleeve and (as constructed in Fighl) depending within and spaced from the same so as to fit within the vtop ofthe neck 2.

7` indicates the cover for the top of the sleeve, the same being constructed so as to be easily opened and closed. A covery screwed within or without the neck is likely at any time to stick, from various causes, and cause trouble and delay in opening or in closing, 'and the cover 7 is preferably hinged to the sleeve by a pivot 8y carried by an ear o1' ears 9, the latter being formed with the sleeve or attached thereto. 10 is a bail of stiff resilient wire or metal rod-section, formed to suitable shape, pivotally connected with the sleeve by end pivots 11 entering perfhrations 12 through the sleeve, and bear- Iing on a. canrlike projection 13 of the cover. @By my'impr'ovcd cap or closure I am able lto readily replace screw-covers which have been found objectionable with those which are much more easily and quickly operated. I am aware that a hinged cover and securing within tha sleeve and flenched io h@ Same and formed with a Screw thread Mm-fw, engaged with thel screw lnezu of h@ me the sleeve being verticnly mjusab tive $0 the neck.
